I got it. Thanks for spending so much time to explain. I guess you are right on this so-calle axiom argument.
Thanks for trying to understand.
So "God exists" is not an axiom unless God is roughly defined first. I agree. In fact, as I review what I said, I did use expression:
God = functions (parameter1, parameter2, ...)
Except I thought those parameters could be added at later time. Indeed, God is a name space and is empty until those parameters and functions are filled. I might make an inaccurate argument. But I do have the right idea.
Yes, you may have "the right idea". But please keep in mind that all I can possibly know about your idea is what you present it as. And please keep in mind - when investigating the ideas of others - that it mightn´t be the idea that is lacking but merely its presentation.
I will tentatively assign two characters to God at the beginning: 1. supernatural; 2. authoritative. Then I say, such a being called God, which exist.
Ok.
Would that be a good axiom?
Don´t know if it´s a good one, but I would be willing to accept that for an unnecessary assumption as the starting point.
(Let´s not forget that there are several different definitions of "axiom". One of them demands that an axiom must be inevitable or self-evident, and - for hopefully obvious reasons - I wouldn´t accept your assumption as such.)
Now let´s get clear about a couple of things that I think I have said earlier but that may have been misunderstandable:
1. I am afraid you underestimate the distance between the paradigms of your and my worldview.
2. I am afraid you underestimate my indifference towards philosophical ideas/systems that are founded on unnecessary assumptions that I don´t share or even find downright absurd. Actually, even though they may prove internally consistent, there will always remain these premises that will render them completely uninteresting to me.
3. I am afraid you underestimate my tolerance towards such philosophical ideas. If you feel that your worldview is answering all your questions that´s a good thing, in my book, and I would recommend you to keep it (at least until - possibly - a change of desires and needs necessitate you to change the paradigms of your thinking at some point in time.
As my age and post count may or may not have already told you I´m not exactly a spring chicken when it comes to theological discussions. Don´t take it personally but I don´t expect something substantially new from your answers. Christianity - and I beg you to excuse this admittedly too broad statement - in my experience asks questions I don´t have, and doesn´t satisfactorily answer the questions I have. Thus, unless you present a substantially new Christian concept, I am not willing to take a long and troublesome journey that has already proven frustrating to me numerous times.
(And, as a side note: should you indeed present some substantially new concepts, we would be discussing
your personal philosophical concepts, but not "
Christianity as a philosophical system".)
Notwithstanding my unwillingness to walk with you through through the details of your theology, I will at least give you a feedback concerning your "axiom" ('There is something a. supernatural and b. authoritative.' I'll call it "God".)
1. Previously you said that everything else in your "Christian philosophy (theology)" followed logically and necessarily from this "axiom", i.e. there won´t be any more unnecessary assumptions involved. Again, please don´t take it personally, but I highly doubt that.
2. I have my problems with the term "supernatural". In my experience it is used as a mere ex-negativo concept (without a
positive definition). It opens the door to non-explanations presented as explanations. IOW, it will allow you to answer any question with the non-answer "This is beyond your/our understanding - it´s the supernatural, after all."
3. I see (and have experienced countless times) a similar problem with the unnecessary assumption that there is an "authoritative" entity: It opens the door to non-explanations presented as explanations. I.e. you will be entitled to answer any why-questions with "Because God says so."
IOW: a discussion based on your premises would mean a stacked deck leaving you with all the argumentative wild-cards.

That´s neither fun nor does it promise to result in inspiration or insight on either part.
Now, don´t mistake my indifference towards the way you construct your worldview from your unnecessary premises for a general disinterest in your ideas and thoughts. It´s just that I would be more interested in finding out why you (or anyone, for that matter) arrives at their premises (or "axioms", as you call them). E.g. I would be highly interested to learn why anyone would even desire there to be a supernatural authority (a desire that is completely alien to me), and what they hope to gain from such existing. Unfortunately, this is not what this thread is about (to the contrary, it explicitly asks me to abstain from taking a closer look at the premises and the psychology behind them), and I will respect that.
Eventually I might make a separate thread for discussing these things.
